TableLayoutPanel und AutoScroll

Ich habe ein TableLayoutPanel, zu der ich Zeilen hinzufügen dynamisch.

Jede Zeile hat eine absolute Größe.

Ich habe die AutoScroll auf "true", aber wenn ich Zeilen hinzufügen, die gehen aus der Anzeige des TableLayoutPanel, ich sehe nicht den Blättern.

Dies ist der designer-code:

namespace WindowsFormsApplication1
{
    partial class Form1
    {
        ///<summary>
        ///Required designer variable.
        ///</summary>
        private System.ComponentModel.IContainer components = null;

        ///<summary>
        ///Clean up any resources being used.
        ///</summary>
        ///<param name="disposing">true if managed resources should be disposed; otherwise, false.</param>
        protected override void Dispose(bool disposing)
        {
            if (disposing && (components != null))
            {
                components.Dispose();
            }
            base.Dispose(disposing);
        }

        #region Windows Form Designer generated code

        ///<summary>
        ///Required method for Designer support - do not modify
        ///the contents of this method with the code editor.
        ///</summary>
        private void InitializeComponent()
        {
            this.tableLayoutPanel1 = new System.Windows.Forms.TableLayoutPanel();
            this.button1 = new System.Windows.Forms.Button();
            this.SuspendLayout();
            //
            //tableLayoutPanel1
            //
            this.tableLayoutPanel1.AutoScroll = true;
            this.tableLayoutPanel1.CellBorderStyle = System.Windows.Forms.TableLayoutPanelCellBorderStyle.Single;
            this.tableLayoutPanel1.ColumnCount = 1;
            this.tableLayoutPanel1.ColumnStyles.Add(new System.Windows.Forms.ColumnStyle(System.Windows.Forms.SizeType.Percent, 50F));
            this.tableLayoutPanel1.Location = new System.Drawing.Point(24, 48);
            this.tableLayoutPanel1.Name = "tableLayoutPanel1";
            this.tableLayoutPanel1.RowCount = 1;
            this.tableLayoutPanel1.RowStyles.Add(new System.Windows.Forms.RowStyle(System.Windows.Forms.SizeType.Percent, 50F));
            this.tableLayoutPanel1.Size = new System.Drawing.Size(239, 163);
            this.tableLayoutPanel1.TabIndex = 0;
            //
            //button1
            //
            this.button1.Location = new System.Drawing.Point(24, 10);
            this.button1.Name = "button1";
            this.button1.Size = new System.Drawing.Size(239, 28);
            this.button1.TabIndex = 1;
            this.button1.Text = "button1";
            this.button1.UseVisualStyleBackColor = true;
            this.button1.Click += new System.EventHandler(this.button1_Click);
            //
            //Form1
            //
            this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 13F);
            this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
            this.ClientSize = new System.Drawing.Size(292, 266);
            this.Controls.Add(this.button1);
            this.Controls.Add(this.tableLayoutPanel1);
            this.Name = "Form1";
            this.Text = "Form1";
            this.ResumeLayout(false);

        }

        #endregion

        private System.Windows.Forms.TableLayoutPanel tableLayoutPanel1;
        private System.Windows.Forms.Button button1;
    }
}

und dies ist, wie ich Zeilen hinzufügen:

using System.Text;
using System.Windows.Forms;

namespace WindowsFormsApplication1
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            tableLayoutPanel1.RowCount++;
            tableLayoutPanel1.RowStyles.Add(new RowStyle(SizeType.Absolute, 30));
            Button b = new Button();
            tableLayoutPanel1.Controls.Add(b, 0, tableLayoutPanel1.RowCount - 1);

        }
    }
}

Weiß jemand was Los ist?

danke 🙂
